Abstract
Se dispone una primera sección superior entre una primera pared lateral de cilindro y una segunda sección superior en la dirección axial de un eje de levas. La segunda sección superior se dispone entre una segunda pared lateral de cilindro y la primera sección superior en la dirección axial del eje de levas. La distancia entre la primera pared lateral de cilindro y la primera sección superior en la dirección axial del eje de levas es más corta que la distancia entre la segunda pared lateral de cilindro y la segunda sección superior en la dirección axial del eje de levas. La distancia a la primera sección superior en una dirección axial de cilindro desde un tercer plano virtual, que incluye el eje de un cigüeñal y es perpendicular a un eje de cilindro, es más corta que la distancia a la segunda sección superior en la dirección axial del cilindro desde el tercer plano virtual.A first upper section is disposed between a first cylinder side wall and a second upper section in the axial direction of a cam shaft. The second upper section is disposed between a second cylinder side wall and the first upper section in the axial direction of the cam shaft. The distance between the first cylinder side wall and the first upper section in the axial direction of the camshaft is shorter than the distance between the second cylinder side wall and the second upper section in the axial direction of the camshaft. The distance to the first upper section in an axial cylinder direction from a third virtual plane, which includes the axis of a crankshaft and is perpendicular to a cylinder axis, is shorter than the distance to the second upper section in the axial direction of the cylinder from the third virtual plane.
